31361100 Copper Pipe Flashing
German Copper Vent Pipe Flashing for Roofs, Copper Base for 3, 4 or 5 inch pipes.
These heavy-duty copper/lead flexible, soldered pipe flashings are made in Germany. We have 3 inch, 4 inch and 5 inch. If you want a permanent pipe flashing, this is it! Applicable for roof slopes from 2:12 to 10:12 (can bend to 12:12 if you snip off bottom of pipe). Cap is removable. The flexible part is lead. Made with 20 ounce copper.
They're made in Germany to European standards and the diameter measurements are smaller than you would expect. Use a 4-inch flashing if you have 3-inch pipe, etc.
